About Banda Sea Liveaboard
The Banda Sea is famous for pristine coral and for big animals, and above all for its schooling hammerhead sharks. It is a deep ocean basin ringed by volcanic islands, and almost untouched by tourism.
Our sister ships King Neptune and Neptune One sail here every season, with satellite internet and Nitrox blended on board by a Bauer membrane compressor. For background reading, see our Banda Sea liveaboard guide.

Experience
The Banda Sea Experience
The Banda Sea is made for experienced divers. Deep dives in cooler water and strong, changeable currents are exactly what draw the hammerheads here, and the reward is a spectacle few divers ever see.
Hammerhead season
The season is short, from September to early November, and October is the best month for hammerheads. Dives focus on sites such as Suanggi, Serua and Hatta, with whales sometimes seen on the crossings.
What to expect
This is a remote region. Reaching Ambon takes several flights, internet at sea can be limited, and the day usually holds three or four dives, depending on the weather.
Our routes
Our trips cross the Ring of Fire to the remote outer islands. Round trips start in Ambon, and longer crossings link the Banda Sea with Raja Ampat, Triton Bay, Alor and beyond.
